Mevada engineering works provides saturn brand uni-body side entry design, wafer type full bore ball valves. These are ideally suitable for space, less stress on pipeline and cost saver installation in all kinds of process and utility serviceswhereby valve gets sandwiched between the flanges with the help of sub-ends.
The salient features are
Floating ball - where sealing takes place by allowing ball to move under pressure towards the down stream seat to achieve positive tight shut-off.
Seats-moulded ptfe and reinforced tfe seats assures positive seating and lower operating torque.
Anti-static device and safety feature, i.E., when static is generated and concentrated on the ball due to solvents and high velocity, the spring-loaded balls are installed on the stem, which keeps continuity throughout the valve and discharges the static.
Pyramidal stem - wherein the first stage of defence against leakage, the tapered face of the stem collar gets lined in contact with the body and blocks all leak paths after the thrust seal [washer] is worn out.
Lower emission seal ring - for fugitive emission.
Blow out proof stem - internally inserted and functions as the back seat for assured stem sealing at all pressures, renewable seat and seals.
Live loaded gland packing - to avoid frequent and positive gland tightening against high number of cycles.
Long heightened lever - facilitates easy operation and insulation/puffing on the valve body and pipeline.
Compliance standards - b 16.34, bs 5351, bs 6755-1; size - 40-150 mm; class - 150; and options - electro polished [buff] finish and ultra clean valves for food and pharmaceutical industries, pneumatic, and electric actuator operations can be provided.
